[0028] Combination Figure 1-3 As shown, the present invention provides a high-sealing anti-theft door, comprising:
[0029] Door frame 1, door leaf 2, 1 pair of hinges, anti-theft lock 3, 8 pairs of sealing strips;
[0030] The right side of the door leaf 2 is connected by a pair of hinges (such as...). Figure 1 As shown, the door frame 1 (including a first hinge and a second hinge) is connected to the right side door frame. Each contact surface between the door frame 1 and the door leaf 2 includes two stepped surfaces. A first pair of sealing strips 6 is installed between the first outer stepped surface 4 of the right side door frame 1 and the first corresponding outer contact surface 5 on the door leaf 2. A second pair of sealing strips 9 is installed between the first inner stepped surface 7 of the right side door frame 1 and the first corresponding inner contact surface 8 on the door leaf 2. A third pair of sealing strips 12 is installed between the second outer stepped surface 10 of the left side door frame 1 and the second corresponding outer contact surface 11 on the door leaf 2. A fourth pair of sealing strips 15 is installed between the second inner stepped surface 13 of the left side door frame 1 and the second corresponding inner contact surface 14 on the door leaf 2. A fifth pair of sealing strips 18 are installed between the third outer step surface 16 of the upper door frame 1 and the third corresponding outer contact surface 17 of the door leaf 2. A sixth pair of sealing strips 21 are installed between the third inner step surface 19 of the upper door frame 1 and the third corresponding inner contact surface 20 of the door leaf 2. A seventh pair of sealing strips 24 are installed between the fourth outer step surface 22 of the lower door frame 1 and the fourth corresponding outer contact surface 23 of the door leaf 2. An eighth pair of sealing strips 27 are installed between the fourth inner step surface 25 of the lower door frame 1 and the fourth corresponding inner contact surface 26 of the door leaf 2. When the security door is opened, the sealing strips separate into two sub-sealing strips and are respectively installed on the door frame step surface and the corresponding door frame step surface of the door leaf.
[0031] It should be noted that elevator doors or stair doors in general public areas can generate noise due to airflow through gaps, friction during opening and closing, or old parts. Noise can also be generated by airflow from pipes in water and electricity wells, gaps between windows and walls, etc., as well as noise from people's behavior or talking, pets' behavior or barking in public areas. In actual use testing, the high-sealing security door of this utility model has a significant improvement in sound insulation and noise reduction compared to traditional security doors.
[0032] Besides noise, other uncivilized behaviors, such as smoking in public areas, neighbors opening their doors to let in cooking fumes, pets defecating in public areas, and piling up smelly garbage in public areas, can cause unpleasant odors outside the security door. If a traditional security door is used, there will be obvious odors entering the room, causing a bad experience for the user. However, the high-sealing security door of this utility model will hardly allow any odors to enter the room, providing users with a good user experience.
[0033] It should be further explained that, such as Figure 1 As shown, the first and second hinges in a pair of hinges are distributed vertically, which allows the door frame to bear the weight of the door leaf more evenly and avoids situations such as the door frame or hinges deforming, which could cause the security door to be unable to close, resulting in inconvenience.
[0034] Preferably, the anti-theft lock 3 is installed on the door leaf 2, and a lock tongue hole is provided on the left side of the door frame 1 corresponding to the position of the anti-theft lock on the door leaf 2.
[0035] It should be noted that the anti-theft lock 3 is generally installed in the middle of the door leaf 2 at a moderate height to facilitate the user's unlocking operation. The left side of the door frame 1 is provided with a lock tongue hole corresponding to the position of the door leaf 2 lock. When the door lock is closed, the lock tongue can be engaged in the lock tongue hole in the left side of the door frame to complete the locking of the anti-theft door.
[0036] Preferably, each of the one pair of hinges includes a door leaf connecting hinge plate, a hinge shaft, and a door frame connecting hinge plate.
[0037] It should be noted that the pair of hinges are connected to the door leaf through the door leaf connecting hinge plate and to the door frame through the door frame connecting hinge plate.
[0038] Preferably, the door leaf connecting hinge plate is detachably connected to the door leaf, and the door frame connecting hinge plate is detachably connected to the door frame.
[0039] It should be noted that this design structure makes the installation of security doors practical and convenient.
[0040] Preferably, both hinges are concealed hinges.
[0041] Preferably, the concealed hinge is installed inside the right side of the door frame.
[0042] It should be noted that the hinges are installed inside the door frame, which can hide and protect the hinges, preventing criminals from breaking into the door by cutting the exposed hinges and causing damage to property or people inside the house.
[0043] Preferably, door handles are installed on both the inner and outer surfaces of the door leaf.
[0044] It should be noted that although the two stepped sealing structures of the contact surface between the door frame 1 and the door leaf 2 make the security door only open outward after being unlocked, people not only need to unlock the security door from the outside and open it by pulling the door handle, but also need to close the security door from the inside. Therefore, door handles are installed on both the inner and outer surfaces of the security door leaf 2.
[0045] Preferably, the anti-theft lock is an intelligent anti-theft lock.
[0046] It should be noted that the use of intelligent anti-theft locks can further enhance the anti-theft performance of the high-sealing anti-theft door of this utility model, and can eliminate the need to carry physical keys through the combination lock. It also avoids the inconvenience of users being unable to enter the room if they forget their keys, as well as the expense of finding a locksmith to unlock the door.
[0047] Preferably, the smart anti-theft lock has a fingerprint verification anti-theft system.
[0048] Preferably, the smart anti-theft lock has a facial recognition anti-theft system.
[0049] It should be noted that both fingerprint verification and facial recognition anti-theft systems can further improve the anti-theft performance of security doors. Other intelligent anti-theft systems (such as voiceprint recognition) can also be used. Users can choose according to their own situation and needs.
[0050] Preferably, it also includes a hydraulic rod, the first end of which is installed on the upper side frame of the door frame 1, near the door leaf 2, and the second end is installed on the inner outer surface of the door leaf 2.
[0051] It should be noted that the function of the hydraulic rod is to slowly close door 2, avoiding excessive noise and vibration during closing.

A fourth pair of sealing strips is installed between the second corresponding inner contact surfaces on the door leaf. A fifth pair of sealing strips is installed between the third outer stepped surface of the upper door frame and the third corresponding outer contact surface on the door leaf. A sixth pair of sealing strips is installed between the third inner stepped surface of the upper door frame and the third corresponding inner contact surface on the door leaf. A seventh pair of sealing strips is installed between the fourth outer stepped surface of the lower door frame and the fourth corresponding outer contact surface on the door leaf. An eighth pair of sealing strips is installed between the fourth inner stepped surface of the lower door frame and the fourth corresponding inner contact surface on the door leaf. When the security door is opened, the sealing strips separate into two sub-sealing strips, which are respectively installed on the contact surfaces of the door frame stepped surface and the corresponding door frame stepped surface on the door leaf. This utility model of a high-sealing security door adopts a sealing structure of paired sealing strips in contact with each other, which greatly improves the airtightness of the security door, enhances its heat insulation and sound insulation performance, and improves its heat insulation and sound insulation performance.
